[Dovecot] 1.0.rc25 released

http://dovecot.org/releases/dovecot-1.0.rc25.tar.gz http://dovecot.org/releases/dovecot-1.0.rc25.tar.gz.sig

Instead of having "Should v1.0 be released already" discussion, how about having "What's still missing from wiki.dovecot.org and how could it be improved" discussion? And what should the wiki exported to doc/ directory in the tarball look like?

* If time moves backwards, Dovecot kills itself instead of giving
  random problems.

+ Added --with-headers configure option to install .h files.
  Binary package builders could use this to create some dovecot-dev
  package to make compiling plugins easier.
- PLAIN authentication: Don't crash dovecot-auth with invalid input.
- IMAP APPEND: Don't crash if saving fails
- IMAP LIST: If prefix.INBOX has children and we're listing under
  prefix.%, don't drop the prefix.
- mbox: Broken X-UID headers still weren't handled correctly.
- mail-log plugin: Fixed deleted/undeleted logging.
